Vital signs (often shortened to just vitals) are a group of the 4 to 6 most important signs that indicate the status of the bodyâs vital (life-sustaining) functions. These measurements are taken to help assess the general physical health of a person, give clues to possible diseases, and show progress toward recovery. The normal ranges for a personâs vital signs vary with age, weight, gender, and overall health. There are four primary vital signs: body temperature, blood pressure, pulse (heart rate), and breathing rate (respiratory rate), often notated as BT, BP, HR, and RR.
These vital signs remain relatively constant throughout adult life. But children are not small adults, and normal vital signs are different as a newborn becomes an infant and then a child. The normal values for blood pressure, pulse rate, and respiratory rate change as the newborn/infant/child grows and ages. Body temperature does not change with age.
